As discussed in Iaadcce9. This does have a few benefits:
* Less code in the already pretty big render.js file.
* The code setting the target attribute is much closer to where it
belongs: in the file that specifies how the content of a reference
popup should look and behave.
* The class name "mwe-popups-extract" is not mentioned in two different
files, but in the same.
Note this changes the signature of this src/ui/templates/… file to not
return an HTML string any more, but a jQuery object. The other templates
still return strings. I believe this is fine, and not that much of a
difference anyway. The signatures don't need to be identical. And the
jQuery object still represents the exact same HTML as before.
If it helps we could change all templates/… signatures accordingly.
Could be done in this or a separate patch.

This solves the (I believe) only regression we introduced: A bad fake
reference like <span class="reference">[[Other article#Section]]</span>
showed a page preview for the "Other article" before we introduced
reference previews, but would have shown nothing after I9ec57e0.
Checking if the link is a self-link solves this and possibly more related
issues. Only self-links can point to a footnote on the same page.
Manually created fake-references like
<span class="reference">[[#Section]]</span> still have a chance to show
nothing in case the manually created HTML does not strictly follow the
expectations in the gateway. There is not much we can do about this. We
should not accept any arbitrary HTML but need to make at least *some*
assumptions.

We updated this documentation just recently via Ie370cfe. We followed
what the createModel() function does. But this is not the only way a
PreviewModel object can be created. Reference previews, for example,
don't use it.
Instead of following createModel(), I checked what the different popup
types actually use.

I do find these very confusing and would like to remove them:
* The test setup looks like these popup types are going to use
these properties. But they don't. They are not even trying to
access these properties.
* There are no assertions that make sure these properties are
*not* used. It would be possible to add something like this,
but I honestly think this is not worth it.
We might need to reflect this in the PreviewModel documentation
in src/preview/model.js. I would like to do this in a separate
patch.

This is as preparation to introduce a gateway switch that decides if the
page or reference gatway should be selected. Moving that code to it's own
realm makes that path better testable.

This installs a series of safety nets:
* The selector [href*="#"] skips links without a fragment.
* It's still possible that a fragment exists, but is empty.
mwTitle.getFragment() checks this.
* The gateway does not assume the element exists, but checks this first.
If there is no such element, the gateway aborts the request in a way
that no error popup is shown. This is currently only possible with the
`{ textStatus: 'abort', xhr: { readyState: 0 } }` response as seen in
this patch. We might need to introduce a new, more clean way to silently
quit a fetchPreviewForTitle() call.
* The test for the reference gateway finally covers the scraping code.

Including tests for all situations.
I believe it is impossible or extremely hard to actually abuse any of
these places. All these data are not extracted from the current page, but
delivered either by MediaWiki's api.php or a RESTful endpoint, as
configured via $wgPopupsGateway and $wgPopupsRestGatewayEndpoint. A
possible attacker would need to write it's own endpoint (which must either
run on the same server or somehow ignore the CSRF token), and set the
value of mw.config.values.wgPopupsRestGatewayEndpoint on the client to
this endpoint – which requires just *another* attack vector to be able to
do this.
It's "the right thing"(tm) to escape all this anyway.

Instead of maintaining a list of named constants (which must be updated
every time we want to add a new test with a new message), the mock now
behaves like MediaWiki's build-in qqx dummy language code and returns
the message key in brackets. The additional benefit of using the
HTML-like <…> characters is that this will automatically test if the
messages are properly HTML escaped.

This will affect all links, including [[Other page#Fragment]] for
example. But it will not have much of an effect there. The mw.Title
class is able to understand strings like "Other page#Fragment". All
old code calls title.getPrefixedDb() on the result. This will *not*
include the fragment. Only the new code will use title.getFragment().
I made sure this does not affect regular page previews, even when the
link is something like [[Other page#Fragment]].

Mocha discourages the usage of arrow functiones in the test specs since
Mocha context can't be accessed from inside.
I stumbled across this when using this.skip(); in the reference preview
selenium tests. Since it took me some time to figure out why it was not
working, I guess it's better to avoid lambdas generally there.

I guess both is fine: either having the default in the gateway (as it
was before), or in the renderer (as this patch proposes). I, personally,
feel better with having it closer to where it is needed. This way it's
not possible to accidentially deliver a model object with an empty title.
The renderer will catch this.
At the moment we don't know exactly how we will fetch other titles (e.g.
"Book").
This change is split from I15611a4 where it was a little misplaced.
It also includes a test for the default fallback title.

Special characters that have a meaning in one of the many different input
formats jQuery accepts must be escaped.
The real-world use-case are references like <ref name=":1"> with a colon.
But it's many more characters that need escaping. See
http://api.jquery.com/category/selectors/
Note this patch misses a test. I already uploaded I9ec57e0 to fix the
currently incomplete tests. But I can't make it work. How do I create an
element in the test environment so that jQuery finds it?
I suggest to merge this and continue working on the tests later, because
this is currently one of the most annoying issues that makes all testing
unreliable.

This is documented at http://usejsdoc.org/tags-type.html, but not in many
other places, especially not in the JSDuck documentation.
The {!…} syntax means "can not be null". This is the default anyway.
The {?…} syntax means nullable. In a few situation is was used when a
parameter can be undefined. I decided to remove it everywhere and replace
it with {…|null} when appropriate, because this is much more explicit. Less
syntax to remember.
Note I'm intentionally not using the […] syntax when a parameter is followed
by non-optional parameters. Actually skipping a parameter in such a situation
would mess the parameter order up. Having optional parameters not at the end
is sometimes used as a feature in JavaScript code, but not in this codebase,
as far as I can see.

This does make generic `array` type hints more specific when possible.
I'm also applying my personal best practice to not have any @return
documentation on test @dataProviders. These don't provide any useful
information, and can't. The best type we could use is `@return array[]`,
but that would be the same for every single data provider. Copy pasting
these comments around is of no real value.
Also it was already inconsistent as some did not had this comment.

The test setup was slightly refactored to be more general about
the type of the popup.
The additional reference links on the test page were added mostly
to be prepared for further tests of more complex cases.
On the CI the tests should be executed with having reference
popups enabled. The code tries to skip test when the feature is
disabled.

it to false on the production servers. This makes it easier to use and
test by CI.

It's not exclusively about page summaries any more.
We had a few suggestions in mind:
* get, fetch, request, or issueRequest. But I feel these are all to
generic and don't describe well what the method does. As a reminder:
It expects a Title object and returns a promise, which returns a
PreviewModel object, which contains an HTML "extract".
* fetchPreview? I feel this can still mean to many things.
* fetchPreviewModel? But we don't really need to repeat that it will
return a model object.
So I went for fetchPreviewForTitle. What do you think?
